Official Solution:
Drop-down 1:
In 2017, Other Advanced Biofuels production accounted for (72/1,831) * 100% of the total production.
In 2010, Other Advanced Biofuels production accounted for (2/1,364) * 100% of the total production.
To determine how many times greater the 2017 percentage was compared to 2010, we calculate:
\(\frac{(\frac{72}{1,831})}{(\frac{2}{1,364})} =\frac{72}{1,831}*\frac{1,364}{2} =36*\frac{1,364}{1,831}\), which is approximately 27.
Drop-down 2:
Evaluating the charts, we identify two candidates for the smallest percentage increase: Conventional Ethanol and Biopower.
Conventional Ethanol increased by \(\frac{1,342 - 1,127}{1,127} * 100 \approx 19\%\).
Biopower increased by \(\frac{214 - 191}{191} * 100 \approx12\%\).
Since 12% is the smallest percentage increase, the least growth occurred for Biopower.
Correct answer:
Dropdown 1: "27"
Dropdown 2: "Biopower"
